How Can I get substring between commas?

DECLARE @tbl TABLE (myText NVARCHAR(30))

INSERT INTO @tbl(myText)
VALUES('Friday,May,05,2013')

;WITH cte AS
(
	SELECT LEFT(myText, CHARINDEX(',', myText)-1) AS Word, RIGHT(myText, LEN(myText) - CHARINDEX(',', myText)) AS Remainder
	FROM @tbl
	WHERE CHARINDEX(',', myText)>0
	UNION ALL
	SELECT LEFT(Remainder, CHARINDEX(',', Remainder)-1) AS Word, RIGHT(Remainder, LEN(Remainder) - CHARINDEX(',', Remainder)) AS Remainder
	FROM cte
	WHERE CHARINDEX(',', Remainder)>0
	UNION ALL
	SELECT Remainder AS Word, NULL AS Remainder
	FROM cte
	WHERE CHARINDEX(',', Remainder)=0
)
SELECT *
FROM cte
WHERE Word = 'May'
